I am repairing an old chair and when I was putting the back on, it cracked. Any ideas on repairing this. I really can’t take it back out again because it will probably just crack further and it is already glued in place.

Without taking it all apart, I would see about some epoxy. Keep working it in until it wont take any more. Then wait and work it in some more. It should be fine and if not, you would have had to resort to scarfing in another piece anyway so you really don’t have anything to lose.

I’ve had good luck thinning Titebond II slightly with water and letting it flow into cracks with a little help from a squeegie, and then clamping as best as I can. I recently fixed the crack in the forearm of an O/U shotgun this way.

I vote for epoxy also. You might try putting the resin and hardener bottles in some very warm water for about 10 minutes,before you mix them, to thin it out. Then inject it into the crack with a syringe and needle. The warm mix will flow better but will cut down the cure time, so if you using the quick set epoxy, don’t waste any time getting it in there.

Thanks Tim, I opened it up as much as possible and got as much as possible in there, if it doesn’t work well I will end up scarfing some pieces on and making it look as good as I can.. Had to look up Scarfing, thanks for the lesson David.

Wish I’d seen this a bit sooner. Typically, when I have to fix (or stabilize) a crack, a check or anything similar to the issues you have here, I do use epoxy (West Systems) But I thin it with Xylene first. You can thin the epoxy to such a degree(almost like water) that when you apply it to the crack with a syringe, the epoxy is drawn in very deep. The epoxy takes longer to set up when it’s mixed with Xylene (depends how much you thin it), but other than that, it works very well.
